Abstract
Biofuels are intended to replace the fuel from petroleum. They are a
sustainable alternative to fossil fuels because they are renewable and less toxic to
the environment. This work aims to contribute to sustainable development by
offering a renewable energy source that addresses the pressing energy issues of the
day, including the reduction of greenhouse gas emissions and the preservation of
non-renewable fossil resources. Biofuel is produced by the transesterification of
triglycerides present in Aegyptiaca (Lalob) oil, by displacing glycerine with a low-
molar-mass alcohol. The resulting ester mixture exhibits physicochemical properties
similar to those of petroleum fuels. This study reviews the synthetic paths that lead
to biofuel by means of the catalytic transesterification of Aegyptiaca (Lalob) oil.
Although methyl esters are currently the only ones produced at an industrial scale,
the use of ethanol, which can also be obtained from renewable resources, has been
considered, as it would generate a cleaner and more biocompatible fuel.
